OR ATTACHMENT THEREFOR.

Application filed July 25, 1913, Serial No. 781,148.

To all whom it may concern:

Be it known that I, Moses C. NIXON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Beds or AttachmentsTherefor, of which the following is a specification. 7

The invention relates to beds, the object being to provide an adjustablebed whereby the posture of the occupant may readily be changed withoutundue strain or annoyance; and consists, preferably, in the constructionhereinafter described, which may be varied without departing from thespirit of my invention.

In the drawings, Figure 1 is a plan view of a bed with my improvementsattached; Fig. 2 is a side elevational view of Fig. 1; Fig. 8 is asection of Fig. 1, enlarged to better show the operating mechanism; Fig.

4 is a side view of Fig. 3; Fig. 5 is an end view of Fig. 4;; Fig. 6 isa sectional view of a part of the operating mechanism on line A-A ofFig. 5; Fig. 7 is another plan view of a bed with my invention attached,with parts broken out to reduce the size of the drawing; Fig. 8 is aside elevational view of Fig. 7, also with parts broken out; Fig. 9 is atop view of a section ofFig. 7 enlarged to better illustrate certainfeatures; Fig. 10 is a side view of Fig. 9, and Fig. 11 is a perspectiveview of one of the end castings of pivot frame 15, showing means toprevent the pivots from slipping from bearings as illustrated in Figs.7, 8, 9 and 10.

Referring to the drawings, similar numerals of reference indicatecorresponding parts in the different views, and, referring to the same,1 and 2 denote the head and foot respectively and 3 the side rails of abed. Firmly secured to and near the ends of side rails 3 are bars 4.-and 5, thus forming a supporting frame for fabric 6, whichfabric maybeof any suitable type. Secured to the side rails is an intermediate bar7,'or

other suitable means, the object of which will hereinafter appear. Therails and bars being, preferably,of angle bars.

Frame or member 8, which may be of any suitable length and form, isshown in Figs.

1 and 2 as pivotally secured to the side rails 3, as by bolts 9, but itcould be raised to near the level of fabric 6 and pivotally se cured tobracket 10, as shown in Figs. 7 and V 8. Fabric 11 is attached at oneend either Specification of Letters Patent.

raised and lowered. The object of modifications in attaching fabric 11is, that when my invention is applied to an old bed the fabric thereonmay be such that fabric 11 cannot be attached to it, in which case theintermediate bar 7 may be secured to the side rails and extensions 11 offabric 11 passed through the old fabric and be secured to said bar, orequivalents substituted, or if preferred fabric 11 could be securedentirely to frame 8, as shown in Fig. 7, thereby utilizing both the oldbed and its fabric. To better illustrate the modification in at tachingfabric 11 it is shown in Fig. 2 as attached to fabric 6 and extensions11 detached, but when-the extensions are used fabric 11 would bedetached from fabric 6 When intermediate bar 7 and extensions 11*, orsub stitutes therefor, are used and frame 8 is lowered there would be atendency for fabric 11 to drag through fabric 6, and to prevent this,cross wires 11 are provided so that when lowered they will rest uponfabric 6 and prevent the dragging through as before explained. Frame 8should be so positioned that when lowered to normal position its of thestrands shown are attached to fabric 6 at 12,- and the others to bar 7at 12, to illustrate the modification. WVhen the free end of frame 8 iselevated there would be a tendency for the mattress to slide toward theopposite end of the bed and to prevent this sliding retainers 13 securedto bar 5 are provided.

To side rails 3 are secured brackets 14, which support pivoted frame 15which carries the operating mechanism, said frame being composed ofcastings 16 which are secured to bar 17. The length of bar 17 and thatof the pivoted frame '15 would depend upon the width of the bed uponwhich they are'used, so that the pivot ends 16 of castings 16 will restin bearings 18 of brackets 14:. The castings 16 are formed with roundholes 19 (see Figs. 6 and 11), into which hub 20 of gears21 are placedand revolve therein. Retainers 22 enter holes 19 from below and lug 23thereon mates with a similar lug 2% on hub 20 thereby forming a clutchconnection therewith.

These gears and retainers are uniformly threaded so as to receive matingthreads on operative connecting rods 25. The retainers are also providedwith rims 26 and the object of providing a clutch connection betweenthese gears and retainers is, that when rods 25 are screwed into themthe gears and retainers will revolve together and can not be separated,thus preventing them from being displaced or forced upward or downwardout of position.

While a single pivoted frame 15, which extends across the width of thebed and supports the operating mechanism at both sides of the bed, isshown, it will be understood, of course, that I do not limit myselftothis specific arrangement, as it is quite evident that any othersuitable pivoted support that will permit said mechanism to adjust itsposition to conform to the changing position of the operative connectionbetween said mechanism and the pivoted member Swill suffice; also thatwhile the hub 20 and. retainers 22 are shown any other arrangementwhereby the gears 21 may be retained in position will sufiice.

I The upper end of rods 25 is pivotally attached to frame 8, as by bolt27, said rods being bent near their upper end and from such benddownwardare threaded to mesh with the threads of the gears and retainers, and itis screwed into the same. Castings '16 also furnish supports andbearings 28 .for shaft 29 which is journaled therein and is operatedby.crank 30, which crank is detachable and may be applied to either end ofshaft 29, thereby making it operative from either side of the bed. Toshaft 29 are secured gears-31, which gears mate with and drive gears 21,causing the latter and retainersv 22 to revolve around rods 25, therebyraising and lowering the pivoted frame Sand adjusting it to desiredposition.

The bend in rods 25 is not essential to the operation but is intended toraise the lower or free end of the rods to. a horizontal position outofthe way, as shown in dotted outline in Figs. 2, 8 and 10, leaving aclear space beneath thebedwhen frame 8 is in lowermost ornormalposition. It will also be noticed that as the pivoted frame 8 is raisedand lowered rods 25 continually change position relative to theverticaland it is important that provision be made to meet such changingwhichis done by pivoting frame 15 in bearings 18- so that said framewill readily adjust. itself to meet the changing position of rods 25. Ip In Figs. 7, 8,9 and 10 rods 25 and the objection. 7 top with anelongated slot 14? to accommooperating mechanism are located at theouter side of rails 3 and to do this a specially devised bracket isdesirable. If the operating mechanism were placed outside an ordinarysupporting bracket it would extend so far out from the side rail as tobe objectionable, but bracket 14 largely over comes this'objection. Alsoif unprotected there would be a liability of the bedding, and wearingapparel of the attendantcoming in contact with the gears and beingdamaged, but in the present case bracket A also acts as a shield andovercomes this Bracket 14 is provided at its date the shifting positionof rods 25, and at the side another opening 14 is provided to permit theshifting movement of shaft 29 and stem of crank 30 as frame 8 is raisedand lowered. A variation in the length of frame 15 or in the width ofthe bed may allow sufiicient lateral play to permit the frames pivotends to slip from their bearings, with resultant jar to the occupant ofthe bed: To overcome this contingency bolts 16 are tapped into'pivotends 16 and on said bolts are washers 16 with larger diameter than thatof the bearing openings 18 whichwill prevent said pivot ends fromslipping from their bearings.

For convenience, fabrics 6 andll are designated as stationary fabric andmovable fabric respectively.
